PIPE & MANHOLE REHABILITATION

Project Description: The township of Pleasant Point experienced high ground water levels which led to major water infiltration through the sewer network and overloading the holding ponds which caused major environmental issues. In some places water was penetrating through manholes and pipework like a high pressure hose. Hadlee & Brunton isolated all of the water infiltration to 25 manholes using a series of injection products then coated them with Ultracoat resin. Water infiltration to the pipe reticulation was prevented using their fiberglass patching system.
